WINDOW-SASH FASTENER.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed March 27, 1919. Serial No. 285,441.

T 0 all whom it may concern:

Be it known that I, HENRY WV. NELSON, a citizen of the United States,residing in the city of Ashby and State of Minnesota, have invented newand useful Improvements in Window-Sash Fasteners, of which the followingis a specification, reference being had to the accompanying drawings.

This invention pertains to sash holders, or sash fasteners.

The principal object of the invention is to provide a simple, practical,and eflicient device for sustaining window sash in any desired positionof elevation, one which will substantially take the place of theordinary sash weight.

\Vith these objects in view, attention is called to the accompanyingdrawings, wherein--.

Figure 1 is a side elevation of my device as applied to a window sash inactual operation, a section of the sash being broken away to show themodus opercmclz' of the device;

Fig. 2 is an edge elevation of the edge adjacent the window frame;

Fig. 3 is an edge elevation of the opposite edge without showing Fig. 2;

Fig. at is a sectional detail showing the construction and arrangementof the several parts of the device.

Referring more particularly to the drawings, my invention consists of asuitable housing 1 adapted to be set within a mortise 2 cut in the sideof the sash The outer face of the housing 1 may be countersunk in theedge of the sash 3, so as to afford a continuous unbroken surface 4.Pivoted medially within the housing 1 is'the trigger 5, same consistingof a short lever pivotally mounted as aforesaid upon a pin 6 extendingtransversely across the housing 1, and secured at either side by burringthe ends over, or otherwise. A spur'port 7 is cut through the lowerportion of the outer surface 4 of the housing 1, and a spur 8 ispivotally mounted by means of the pin 9 to the lower end of the trigger5, and is adapted to play through the spur port 7. To the upper end ofthe trigger 5 is likewise pivotally mounted by means of the pin 10, thehorizontal push lever 11, same extending through a horizontal mortise 12cut through the sash 3, so that the end of the push lever 11 extendsinwardly of said sash. A thimble 13 may be located at the inner end ofthe mortise 12 to add to the finished appearance of the attachment, anda button 17 may likewise be mounted at the outer end of the push lever11. A spring 14: is mounted within the housing 1, and normally adaptedto expand the device in such manner as to throw the spur 8 out throughthe spur port 7, at the same time projecting the push lever 11 throughthe mortise 12 out through the thimble 13.

In operation, the sash 3 is mortised as aforesaid, and the device is setwithin such mortise, and is secured in position by suitable screws 15.The operation of the spur 8 is such as to normally engage the guide 16of the window frame, thus holding the sash against downward motion, andso that the sash will stand at any required point. If it is desired tolower the sash still farther, the push lever 11 is projected into themortise 12, thus releasing the spur 8 from engagement with the guide 16,and permitting the sash to be lowered. As the inclination of the spur isdownward, it is obvious that the sash may be readily raised by merelyexerting an upward force upon the same, the spur 8 slidingly passingover the guide 16. The spur 8 being pivotally mounted, its outer facealways sets squarely to and against the sash guide of the window frame.

While I have herein described a certain specific manner and method ofconstructing the elements of my invention, it is understood that I mayvary from the same in minor details, not departing from the spirit of myinvention, so as best to construct a practical device for thepurpose'intended, as defined in the appended claims.

What I claim to (be new and patentable is:

1. In combination with a window sash having an outer vertical edgeproperly mortised out to receive the device, a sash fastener comprisinga housing adapted to set within said mortise with a spur port in itsouter face, a vertically disposed movable spur within said housing,means carried by the housing for normally holding the spur in projectedposition through the port against the sash guide, a push lever connectedwith said parts and extending inwardly through the vertical sash edgefor releasing the spur, said lever and spur being disposed in a singlevertical plane.

2. In combination with a window sash having an outer vertical edgeproperly mortiscd out to receive the device, a sash fastener comprisinga housing adapted to set within said mortise with a spur port in itsouter face, a vertically disposed trigger medially pivoted within thehousing and offset outwardly at its lower end, a spur pivoted on thelower end of said trigger and adapted to play through the port in saidhousing, a spring within said housing adapted to 'bear against the upperinner face of the trigger to normally force the spur outwardly, a pushlever connected with the upper end of the said trigger and extendinginwardly through the vertical sash edge, said lever, trigger and spurbeing disposed in a single vertical plane.

3. In combination with a window sash having an outer vertical edgeproperly mortised out to receive the device, a sash fastener comp-risinga housing having a fiat outer face adapted to lie flush with the Copiesof this patent may be obtained for five cents each, by addressing theouter face of the said sash and having a spur port thereln, sideportiions .on sald housing extending at right angles to the face andpositioned in the mortise, a vertically disposed trigger mediallypivoted between the sides of the housing and offset outwardly at itslower end, a spur pivoted on the lower end of said trigger and adaptedto play through the port in the face of the housing, a spring positionedwithin the housing between the face thereof and the upper inner face ofthe trigger and adapted to normally bear against said trigger to forcethe spur outwardly, and a push lever connected with the upper end ofsaid trigger and extending inwardly through the vertical sash edge.
